The picture of the question in the attached figure
step 1
Find the slope
The formula to calculate the slope between two points is equal to

we have
(-2,-2) and (2,2)
substitute the values

step 2
Find the equation of the line in point slope form

we have

substitute the values in the formula

Answer:
1=51°
2=18°
3=123°
4=39°
Step-by-step explanation:
She will need to sell 18 necklaces a month to reach 1650
The answer is 4 groups because 21+7=28,28÷4=7,and 7×4=28
Answer:
A. T=7.12°C; B. t=3.32min
Step-by-step explanation:
In order to find the answer we can use the Newton's law of cooling:
where:
y0=initial temperature - room temperature
k=coefficients
t=time
Because the outdoors temperature is 3°C, the initial temperature is 20°C, and because the thermometer reads 11°C after 1min we have:



A. Temperature after an extra minute.

so the answer is 7.12°C
B. Time in order to read 4°C
